A representation for minimal light-like surfaces in Minkowsky space is derived. An existence theorem for ruled surfaces in Euclidean four-dimensional space with a given base curve and a constant ratio of Gauss torsion and curvature is proved. An application of ruled surfaces for describe the behaviour of electrons moving in a constant magnetic field is proposed. Product Description popup.authors Бабенко В.І. Болотов Д.В. Горькавий В.О.
